Pip 在安装包时挂起

Question

我在虚拟环境中使用 Django。我正在使用 powershell 并尝试安装 pyopenssl。

内部虚拟环境：

pip 版本 = 19.2.3

python版本=3.8.3

外部虚拟环境：

pip 版本 = 21.2.4

python版本=3.8.3

我尝试使用 python -m pip install -U pip 和 pip install --upgrade pip 在虚拟环境中升级 pip但是它在没有产生任何输出的情况下被挂起这里是 screenshot.

我试试pip install pyopenssl:

它挂在 Installing build dependencies ...。我已经等了 30 分钟，但什么也没发生。

我也试过了python -m pip install pyopenssl

我又一次卡在这个输出上，没有安装 pyOpenSSL。

但是，pip install pyopenssl 在虚拟环境之外工作 screenshot

我卡在这个冻结状态了 2 天。如果您知道解决方案，请回答。谢谢

Answer 1

这是对我有用的

第 1 步：首先我卸载了 pip：

pip uninstall pip

要确保 pip 已卸载，请键入 pip 并确保获得 ModuleNotFoundError: No module named 'pip'

第二步：下载PIP get-pip.py:

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py

第 3 步：安装 PIP：

python get-pip.py

确保 pip 已安装运行 pip --version 确保它是最新的，截至目前 (21.2.4)。

我终于能够安装 pyopenssl :))

pip install pyopenssl
